Staying on one of the canals in Bangkok is an interesting experience. Wasawat's place affords that unique opportunity, which isn't an easy thing to find. His mom and sister are warm and welcoming and make every effort to make your stay a positive experience.
This is not a luxury Airbnb space with sufficient but not ample air conditioning, linens, bedding, bath supplies, room lighting, etc. and because it is located away from the center of Bangkok, we found it difficult (and 4 times the cost) to get a taxi home in the evenings.
If you're looking for a fun experience with only basic amenities then you'll be just fine. We were just expecting a bit more comfort from our Airbnb.
